Over the years, we have found that NorthFin is the preferred food of choice for most of the fish that we see day to day. Most of our tanks are community tanks, which house lots of different types of fish. Carnivores, Herbivores and Omnivores. We have created a special blend of flakes, that we use day to day here in our fish room. You can get four different verities of food for the price of one! Your fish will love it!
